[isabelle-dev] html output of theories

PIDE does an awful lot already, and I’d worry about burdening it with yet more functions. 

It’s easy to get PDF from HTML, provided the quality is high enough. The other direction does not work.

But at the moment this is not very comfortable (no links from constants to their definition, nor from lemma names to the corresponding lemma, ...). However this is all there in Isabelle/jEdit. And my only reason for not using Isabelle/jEdit for the above purpose is that I have to wait until everything is loaded, whereas somebody else already generated the HTML for HOL/Library, AFP, etc. I also agree that HTML output is important for people who don't know Isabelle yet.
> (3) This is what we all use every day, right? So this should be most sophisticated (and already is, I think). Presentation wise the only negative point I can think of, is that ugly LaTeX code is mostly unreadable in the theory-file, while I need it sometimes for (1). In that respect it would be wonderful if either Isabelle/jEdit would magically present the result of TeXing or support nicely rendered syntax for formatting (I think there is no way around LaTeX when it comes to rendering formulas. Maybe there is. Do you know MathML?).
